Publishing Web Server through Cisco 877 router

I'd like to know if it is possible to use both NAT overload to provide clients with internet access with 1 static global IP and at the same time use a static NAT translation to publish port 80 to a specific web server on the LAN so that it is accessible from the internet???

Would I need 2 global IPs?? 1 to use with the NAT Overload and then one to use for static NAT of my webserver??

SHould it still work if my nat statement is configured to use the global IP of the Dialer0 interface rather than actually defining a Pool for the global IP and then using that in my main NAT statement.

Because my dialer0 interface is statically configured with the global IP, is it still possible to define a NAT pool with that exact same global IP? Will the router report conflicts?

I'd like to know this before hand before killing everyone's internet access to then realise it cannot be done.

Yes it will fine as Kusankar has said. The only reason i didn't use that config was because i though it was a separate address than the dialer0 interface address but if it is the same address you just do
